To all whom it may oon/cern.-

Be it known that I, SAMUEL G. SEVIER, a citizen of the United States, residing at Oena- VMy invention relates to improvements in Reference is had to the accompanying draw'- Figure l represents a side elevation of the Fig. 2 represents', a plan View of the Fig. 3 is a perspective view las seen Fig. 4 represents Fig. 5 rep- Fig. 7 repre- 9 represents a* detail perspective view of the A represents the stationary moldboard,

B represents the plow-beam to which the C represents the handles, which are conare connected to the frame E, and the forward end of the said frame is secured by means of thebolt e to the beam B.

The shaft F passes through the junction of the frameE `and the handles C and assists in ,the revolving moldboard Q, which moldboard has a sharp edge q, Yas shown most clearly in Figs. 3 and 5. -The distance of the outer face of the revolving moldboard Q from the rear face of the fixed moldboard is adjusted by means of one or more horseshoe shaped washers q. (Shown in detail in Fig. 6.) If this washer be placed between the frame P and the moldboard Q, then it will be evident that the revolving moldboard will vbe closest to the lixed moldboard, and if it be placed be`- tween the frame P and the gear-wheel L, then the revolving moldboard will be at some distance from the fixed moldboard. These adjustments are desirable, since the frame P is moved about a pivot, thus varying the distance between the fixed and revolving moldeboards. This shaft M is j ournaled in the frame P,which is attached at p to the handles C and at p is pivot-ed to the beam B by the bolt e, or the frame P may be madeA integral with the adjacent half of the frame E. Moreover, it is supported by the frame S, (shown in Figs. 1 to 4,) or S. (Shown in Figs. 7 and 8.) In either case the frame is bent over and secured to the frame D by a bolt s3, passing through the diagonal slot s2 in the bent-over portion of the frame, the said bolt s3 being held by a nut in position on the frame D.

In the device shown in Figs. l to 5 the frame S is provided with a projecting arm s0, which is dentated, as at s4, to receive the wire r, which is wound around the screw s and is secured to the neck of the stud m., which stud isfast to the shaft M and revolves freely within the loop formed at the end of the said wire r. j

It will be seen that the wire may be led into any one of these notches s4, and thus its distance from the face of the revolving moldboard Q may be varied at will. The function of this wire is to scrape off clods of dirt or other matter that might adhere to the revolving moldboard. Instead of this wire, however, Ipreferably use the knife R. (Shown in Figs. 8 and 9.) This knife is provided with a bearing r to receive the pin fm., and has a cutting-edge r2, adapted to scrape the soil off the revolving moldboard. The upper end of this knife is attached to a sliding frame R', which is slotted, as'atI frs, to admit the shanks of the two holding-screws 7'* and 7*", and be tween the screw and the end of the slot a spring fr is interposed, which spring tends to draw the knife toward the face of the revolving moldboard and yet to allow the knife to yield outward when necessary.

rlhe frame R is mounted on the frame S',

similar to the frame S already described, ex-

cept that the arm s0 is omitted.

The driving-wheel H is kept clean by means of the plate Il', secured to the handles C, and the scraper Ilz, which is sharpened, as at h2, and is pressed toward the periphery of the wheel by the spring IIS. This spring is secured to the plow-handles, as at h, and also to the upper end of the scraper Ilz, the said scraper being pivoted on the bolt c.

The object of having the plurality of holes (lfor the said bolt is to raise or lower the wheel II relative to the plow, and thus to raise or lower the point of the plow for shallow or deep plowing.

The operation of the device will be evident from an inspection of the drawings.

It will be seen that the driving-gear is well protected and is not likely to become clogged up with grass,weeds', or dirt, that the point of the plow may b'e readily` and rapidly adjusted, and that the scraper II2 will yield to excessive pressure and may be readily cleaned oif, if choked, by the plowman. These and the various other advantages of the herein-described construction will readily suggest themselves to any one skilled in the art.

It will be obvious that various modiea tions might be made which could be used without departing from the spirit of my invention.

Having thus described iny invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. In a plow, the combination with a driving wheel mounted in bearings vertically adjustable relative to the plow share, in rear thereof, a gear wheel driven thereby, a revolving circular mold board, and a smaller gear wheel interposed between said revolving moldboard and the first gear wheel, for driving the said mold board, substantially as and for the purposes described.

L. In aplow, the combination with a driving wheel mounted in bea-rings in rear of the plow share; a scraper, and a spring normally pressing said scraper on said driving wheel; a gear wheel driven by said driving wheel; a revolving mold board, and a second gear wheel interposed between said revolving moldboard and Vthe first gear wheel, for driving the said moldboard, substantially as and for the purposes described.

3. In a plow, the combination with a beam and a fixed mold board and plow share connected thereto, of the frame D fixed to and the frame E pivoted to said beam; the handles C pivotally connected to said frame D and also connected to said frame E, the frame l) connected to the beam and plow handles, and the frame S connecting said frame I with said frame D, the driving wheel Il and gear wheel K journaled in said frame E and in the lower ends of said handles, and the gear wheel L and revolving moldboard Q journaled in said frame l, substantially as and for the purposes described.
